Coordinating Channel Scanning Among Multiple Radios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networking systems, multiple radios simultaneously scanning the same channel lead to resource wastage, inefficiency, and service disruptions, as they may miss anomalies until the next scan and cause interruptions to clients.
Innovation Solution
A controller identifies a first scan time for multiple radios and adjusts it to determine a second scan time, coordinating channel scanning to prevent simultaneous scanning on the same channel, thereby optimizing resource usage and response times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radios simultaneously scan the same channel, then channel monitoring coverage is improved, but resource wastage and system efficiency deteriorate
Solution Approach 1:
The patent segments the channel scanning function by assigning different time slots to different radios. The controller divides the scanning task so that each radio scans specific channels at different times, ensuring complete channel monitoring coverage while preventing simultaneous scanning of the same channel by multiple radios.
Solution Approach 2:
The patent implements periodic channel scanning where radios alternate their scanning activities in time slots. The controller coordinates periodic scanning cycles, allowing each radio to scan channels at scheduled intervals rather than continuously simultaneously, thus maintaining monitoring effectiveness while reducing resource conflicts.
2Measurement precision
If multiple radios simultaneously scan the same channel, then detection capability is improved, but response time to anomalies deteriorates
Solution Approach 1:
The controller performs preliminary coordination by calculating and distributing optimized scan schedules to radios before scanning begins. This preliminary action ensures that radios are positioned to detect anomalies efficiently in their assigned time slots, maintaining high detection capability while avoiding time-wasting conflicts.
Solution Approach 2:
The system implements feedback mechanisms where radios report their scanning status and detected anomalies to the controller. The controller uses this feedback to dynamically adjust scan schedules and coordinate responses, ensuring that anomaly detection is maintained while response times are optimized based on real-time system state.
3Reliability
If multiple radios simultaneously scan the same channel, then scanning thoroughness is improved, but service continuity deteriorates
Solution Approach 1:
The patent implements dynamic scan scheduling where the controller continuously monitors radio status and channel conditions, then dynamically adjusts scan assignments and time slots. This dynamic coordination ensures thorough scanning is maintained while service continuity is preserved by adapting to changing system conditions and preventing simultaneous scanning conflicts.

AI summary
Examples herein disclose preventing multiple radios from simultaneously scanning a same channel. The examples identify a first scan time associated with the multiple radios and determine a second scan time based on the first scan time. The examples prevent the multiple radios from simultaneously scanning the same channel through a coordination of channel scanning of each of the multiple radios based on the second scan time.
